Introduction
|
|
============
|
|
|
|
Any real-time executive must provide a mechanism for quick response to
|
|
externally generated interrupts to satisfy the critical time constraints of the
|
|
application. The interrupt manager provides this mechanism for RTEMS. This
|
|
manager permits quick interrupt response times by providing the critical
|
|
ability to alter task execution which allows a task to be preempted upon exit
|
|
from an ISR. The interrupt manager includes the following directive:
|
|
|
|
- :ref:`rtems_interrupt_catch`
|
|
|
|
- :ref:`rtems_interrupt_disable`
|
|
|
